CA 2282291

A system (10) for detecting damage to a gas turbine (12) of a jet engine has a radar transmitter (14, 22) and a radar receiver (14, 24). Radar signals (16) are transmitted at the turbine (12) and are reflected. Reflected signals are analysed in signal processing means (18). Damage in the turbine is determined by comparing a data sequence of measured siganals with a standard data sequence of previously measured signals.

La présente invention concerne un système (10) destiné à détecter les dégats affectant la turbine à gaz (12) d'un turboréacteur. Ce système comprend un émetteur radar (14, 22) et un récepteur radar (14, 24). Les signaux radar (16) émis vers la turbine (12) sont réfléchis. Les signaux réfléchis sont ensuite analysés dans un dispositif de traitement du signal (18). On constate les dégats de la turbine en comparant à une séquence de données normalisée des signaux déjà mesurés une séquence de données des signaux mesurés.
